It is secured to mechanisms for the purposes enumerated the cylinder 1 and has a cover 24 secured and which will be further pointed out in the thereto. Mounted above the cover is a T- specification, and illustrated in the accompipe 25, in which is inserted inlet-pipe 26 for 85 35 panying drawings, in whichthe inflowing of the liquid to be treated, and Figure 1 is a central vertical section as to above the T-pipe is located a suit-able reliefthe principalparts.

They have loo 5o e'ning-rilos 6 7 8 9. Removable covers 10 11, lnultiple perforations 31, through which the 'with ribs 12 13 14 15, are secured to the heads, incoming liquid must pass and where it is electrolyzed, the heavier decomposed substances and matter held in suspension falling by gravity to the bottom of cylinder l and the lighter ones rising to dome 47. The electrodes 29 30 arc connected to any suitable system of electrical generation, the current being conveyed by conductors 32 33, having insulations 35, and nut 3G screwed on cond uctors 32 33, which are screw-threaded for the purpose.

At the sides of cover 24 are insulated stuffing-boxes 37, (best seen in Fig. 5,) they being provided with follower-caps 3S, compressing insulating-packing 39 to prevent the outflow of liquids, an insulation 40 being provided for part38 and an insulation 4l for part 37. A tube 42 delivers the electrolyzed liquid to the interior of cylinder l, Where the released impurities descend to the bottom and can at any desirable time be drawn off through pipes 43, controlled by valves 44 and connected to discharge-pipe 45, so that one or more of pipes 43 and valves 44 maybe used, and when a thorough cleaning is necessary wash-out plugs 4G may be removed, giving access for the introduction of hose or other means. Near chamber 17, at the opposite end of cylinder l from inlet-chamber 23, is placed a dome 47, in which the light floating impurities are gathered and where they may be drawn off by pipe 48, controlled by valve 49, while delivery-pipe 50, secured to ange 5l, descends below the dome and into the cylinder to the body ot` pure liquid and, joining pipe 52, affords an outlet therefor. The action of the apparatus is continuous during the supply of liquid and the electric current and is automatic when once set in operation, as the electrical current will iiow in suiicient volume to attack the impurities as presented, a heavy current for many impurities and a lighter current as purification progresses or the liquid is more nearly pure.
